Description
Silicone stopper for suction flask 2000 ml is a laboratory sealing component designed specifically for use with 2000 ml suction flasks. This silicone stopper provides a flexible, reliable seal for vacuum filtration and aspiration work in chemical and biological laboratories. Supplied as a single piece with a net weight of 0,134 kg, it belongs to the product group of plastic stoppers and ground-joint sealing accessories. The silicone construction offers the elasticity needed for repeated insertion and removal while maintaining vacuum integrity on compatible suction bottles. Laboratories use this stopper to close 2000 ml suction flasks during filtration, sample concentration or solvent removal procedures. The item from manufacturer Rettberg originates from Germany and is intended for secure fitting on standard 2000 ml suction flasks. Its design supports routine vacuum-assisted liquid handling and complements common glassware setups found in analytical and preparative environments. Offered as one piece, the stopper is suitable for initial equipping of filtration stations or as a replacement part when existing seals require renewal.

Questions about Stopper, for suction flask 2000 ml
What is this article?
Stopper, for suction flask 2000 ml is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Erlenmeyer flasks, inside Beakers & flasks, in Labware.
An Erlenmeyer, or conical, flask has a flat base and a narrowing wall so a liquid can be swirled. It is the ordinary culture and titration flask. A baffled wall is a different article, used when the swirl must turn the liquid over.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
